Name
sysfiles - Format of UUCP Sysfiles file.
Description
The /usr/lib/uucp/Sysfiles file lets you assign different
files to be used by uucp(C) and cu(C) as Systems, Devices,
and Dialers files.
You can use different Systems files so that requests for
login services can be made to different addresses than UUCP
services.
With different Dialers files you can use different
handshaking for cu and uucp. Multiple Systems, Dialers, and
Devices files are useful if any one file becomes too large.
An active Sysfiles file is not included in the distribution.
Instead a Sysfiles.eg file is included, which contains
comments and commented examples of how such a file can be
used. This is done because UUCP runs faster without reading
this file.
The format of the Sysfiles file is
service=w systems=x:x dialers=y:y devices=z:z
where w is replaced by uucico(ADM), cu, or both separated by
a colon; x is one or more files to be used as the Systems
file, with each file name separated by a colon and read in
the order presented; y is one or more files to be used as
the Dialers file; and z is one or more files to be used as
the Devices file. Each file is assumed to be relative to
the /usr/lib/uucp directory, unless a full path is given. A
backslash-carriage return (\<CR>) can be used to continue an
entry on to the next line.
An example of using a local Systems file in addition to the
usual Systems file follows:
service=uucico:cu systems=Systems:Local_Systems
If this is in /usr/lib/uucp/Sysfiles, then both uucico and
cu will first look in /usr/lib/uucp/Systems. If the system
they're trying to call doesn't have an entry in that file,
or if the entries in the file fail, then they'll look in
/usr/lib/uucp/Local_Systems.
When different Systems files are defined for uucico and cu
services, your machine will store two different lists of
Systems. You can print the uucico list using the uuname
command or the cu list using the uuname -c command.

Examples
The following example uses different Systems and Dialers
files to separate the uucico and cu-specific info, with
information that they use in common still in the ``usual''
Systems and Dialers files.
service=uucico systems=Systems.cico:Systems \
dialers=Dialers.cico:Dialers
service=cu systems=Systems.cu:Systems \
dialers=Dialers.cu:Dialers
This next example uses the same systems files for uucico and
cu, but has split the Systems file into local, company-wide,
and global files.
service=uucico systems=Systems.local:Systems.company:Systems
service=cu systems=Systems.local:Systems.company:Systems
